MnO2 is a promising electrode material for supercapacitors, because it exhibits high theoretical specific capacitance (1380 F g(-1)) for electrical charge while also being inexpensive and environmentally benign. However, owing to its low electrical conductivity, the intrinsic pseudocapacity of MnO2 is not fully utilized. In this work, hierarchically structured spheres composed of MnO2 nanoplatelets and carbon coated cobalt nanobeads (MnO2-NPs@Co/C) are chosen as electrode materials for… CONTINUE READING
